Overview
Three HEPA filters capture fine particles while a carbon pre-filter traps hair and lint and reduces odors. An air quality sensor drives auto mode, and turbo mode boosts fan speed when the air gets worse.
Real HEPA capture and an auto sensor make it practical for allergy season and smoky days. The headline coverage reflects slow circulation, so for allergy relief size it to the smaller room figure.
Who it's for
Pet owners, allergy sufferers and homes hit by wildfire smoke get frequent air changes in a mid sized room. People expecting it to treat a whole open floor plan at allergy grade speed should size up.
Pros and cons
- True HEPA filtration
- Air quality sensor and auto mode
- Turbo mode for fast cleanup
- Control panel dimmer for bedrooms
- Several filters to replace on schedule
- Headline area at low air change rate
- Bullets and description quote different capture figures
Performance notes
Air changes per hour govern allergy relief, so the smaller room figure matters more than the largest area. The carbon pre-filter catches big particles and odors before they clog the HEPA layers. Auto mode raises speed when the sensor sees particles.
